Modification of ceramic membranes by alcohol adsorption

Desolventizing organic solvent-soybean oil miscella using ultrafiltration ceramic membranes

“…In the present case, the isopropanol may be strongly adsorbing to the pore walls, as suggested by Darvinov et al [41], improving interaction of the membrane with the oil, which could be enhancing solute permeation causing the retention to decrease.…”

“…Dafinov et al [41] studied the adsorption and chemisorption of alcohols by alpha alumina, which is a component of the 20 kDa membrane. The strength of the interaction was measured by the temperature required to evaporate the solvent from alpha alumina.…”

Preparation and characterization of hydrophobic ceramic hollow fibre membrane

“…For example, chloroalkylsilanes, fluoroalkylsilanes (FAS), alcohol, polydimethylsiloxane (PDMS), etc. [20,[22][23][24][25][26][27][28][29]. However, in this study, we are interested in fluoroalkylsilanes only as they were reported to be effective in the surface modification of flat-sheet and tubular membranes [25,27].…”

“…The surface modification studies carried out so far involve only flat-sheet and tubular membranes [17,[22][23][24]26,27,[30][31][32]. However, the study on the surface modification of ceramic hollow fibre membranes has not been reported.…”

Sorption and hydration effects on liquid carbon dioxide transport through mesoporous γ-alumina and titania membranes

“…In submicron pores, these interactions yield a disjoining pressure, which is dominated by van der Waals and structural surface forces [1,2]. Physical and chemical solvent sorption may further influence the effective pore radius, porosity, and surface chemistry [3,4]. Results have shown that the ultimate effect of solvent-membrane interactions is low permeability and deviation from Darcy's law (viscous flow), which states that liquid flux through a given membrane is dependent on viscosity and the transmembrane pressure [2,3,5,6].…”
